40 questions. You set up a proportion, mutiply 34 by a 100 and get 3400. Then you divide 3400 by 85 and you get ur answer. You could also try guessing by putting in random values you think are the whole number and multiplying them by 0.85. So if you guess 44 is the whole and try checking it by multiplying it by .85 and get a value thats higher than the value the percentage is equal to you try another smaller value. So if 44 doesn't work you can try 40. 40 times .85 is 34 so your answer of 40 questions is correct.

Identify and solve the inequality that represents how many $20 bills, n, you can withdraw from the account without going below t

Alex Ar [27]

Answer:

$100 + 20n \leq 230$

$n \leq 6$

Step-by-step explanation:

Given

$Balance = \$230.00$

$Minimum = \$100$

$Withdrawal = \$20\ each$

Required

Represent using an inequality and solve

Let the number of dollars be represented by n

<em>If 1 withdrawal is $20 bill</em>

<em>n withdrawals would be $20n bills</em>

The total withdrawal and the minimum balance must be less than or equal to the available balance.

So, this gives

$Minimum + Total\ Withdrawal \leq Available\ Balance$

Substitute values for each of these

$100 + 20n \leq 230$

Solving for n

$20n \leq 230 - 100$

$20n \leq 130$

Divide through by 20

$n \leq 6.5$

But n can not be decimal because it represents number of dollar bills , which must always be an integer.

So, we round down the value of n

$n \leq 6$
